The Hikvision DS-QAE0A120G1-VB6/EU is a professional-grade 120W analog amplifier designed for six-zone public address systems, ideal for use in public, commercial, or institutional environments. It offers flexible audio management with two 6.5 mm microphone inputs, two auxiliary (AUX) inputs, an emergency input (EMC), and support for digital sources via Bluetooth, USB 2.0, and SD card. Output options include 70V and 110V constant voltage, 4 to 16Ω constant impedance, six zone outputs, and a line output, enabling seamless integration into complex audio systems. The unit allows for independent volume control for each zone and source, including separate adjustments for bass and treble, ensuring precise sound management. Microphone and emergency inputs are prioritized, ensuring that critical messages are always transmitted clearly. Advanced protection features guard against short circuits, overloads, and overheating, while a built-in limiter safeguards the connected speakers. A forced-air cooling system with a fan ensures stable and continuous operation. With a frequency response of 80Hz–18kHz (±3dB), total harmonic distortion ≤ 0.5%, and a signal-to-noise ratio of ≥ 83dB, the amplifier delivers high-quality sound. Built with a durable iron chassis, it measures 484 × 88 × 360 mm and weighs approximately 9.2 kg, making it suitable for standard rack installations. The package includes the main unit and a power cable. The amplifier operates on 200V to 230V AC, 50/60Hz, and is designed to function in ambient temperatures ranging from -10°C to +40°C, with relative humidity between 20% and 80%.
